host in the spring ; when the host makes its pupal cell and the 

 internal parts become semi-fluid, the parasite moults and grows very 

 rapidly, completely destroying the host (July). The pupa digs toward 

 the surface by wriggling movements of the body, and the adult 

 emerges when the surface is reached. Title only), by Victor E.

On Monday evening the Annual Address was given before the 

 Society by Professor Herbert Osborn, of the Ohio State University, 

 his subject being " The Habits of Insects as a Factor in Classifica- 

 tion." The address was followed by a most enjoyable smoker, at 

 which the members of the Society and their friends were the guests 

 of the Entomological Section of the Chicago Academy of Sciences. 



Melit^a paethenie var. varia : a Correction. — The statement 

 on p. 57 of the current volume by me that M. ixirthenie var. varia was 

 met with is a mistake, the specimen referred to being only a slightly 

 under-sized dusky form of M. jmrthenie. Mr. Wheeler tells me that 

 the true "varia" does not occur in the immediate vicinity of B6risal.

A Few Notes on Breeding Experiences in 1907. — Before 

 writing my notes a short description of my breeding apparatus will 

 make them more readily understood. I have for ova and newly- 

 hatched larvae three-inch glass-lidded metal boxes ; for small broods 

 and intermediate stages glass candle-chimneys (such as are used to 

 protect candles from the wind) stuck into a perforated zinc rim, 

 which in turn is embedded in a four-inch flower-pot filled with a mix- 

 ture of peat and sand, and in the centre a small phial for food-plant. 

 For larger broods and larger larvae, two horticultural bell-glasses in- 

 serced in their stands, three or four small bread-pans or pork-crocks 

 filled with peat and sand to the depth of the glass phials, and three 

 or four large-sized deep flower-pots ; besides sleeves innumerable. 

 All above except metal boxes are covered with tiffany. 



Anticlea rubidata. — Female, captured July, 1906 ; ova laid freely, 

 and hatching produced healthy larvae, which fed on bedstraw ; were 

 only moved once, from box to bell-glass, and were no trouble at all. 

 Bedstraw being difficult to put in water and also to remove, I con- 

 tented myself with just putting fresh food on the top of the old every 

 other day. Very successful, and a fine emergence in July, 1907. This 

 nsect must be bred to get it at its best. 



LopJiopteryx camelina. — A very early female, taken at rest April, 

 1907, deposited about thirty ova ; the larvae were sleeved when about
